I spoke to someone today whose daughter was on the same team as CL's daughter. According to this person, they carpooled, so CL was not at the gym every week, but she was sometimes, and when she was, she usually stayed and watched the last 15 minutes or so of practice. I'm also told that AL was there a couple of times. BC and CC took turns dropping off their granddaughter, and they did not stay at the gym. However, BC attended all the competitions as did AL, CL, and CL's mother. If I understood correctly, there was at least one time that the parents all went out to eat together at a competition. I'm told that it's a very small gym, and that everyone knows everyone. All the families had cookouts, swim parties, etc together. All the girls sometimes stayed over night together at the owner's house including that weekend. I'm told that it is altogether likely that they all ran across each other. I think the gym owner might have an interest in trying to keep her gym as far out of this as possible.
So, here's a scenario. BC liked bling, so maybe she wore a lot of jewelry and looked rich when they had seen her. They set up an appointment using fake names to view houses planning to rob her. BC may have suggested the Scott house because she knew it was vacant and close to her home. With a cash buyer, she knew that was a good deal and she wanted to make a sale. BC had to show that house first because there was no electricity. Perhaps they had asked about a house on Kerr Station road in Cabot (that is right behind my house-yikes) that was more remote. Either CL alone or CL and AL together met BC at the Scott house where there were close neighbors, so they went to the second house on Kerr Station with BC. If CL was alone with BC, then AL could have been waiting there. He went to rob her as soon as she got out of the car, something went wrong, and she died. They panicked and had to get rid of the body. AL was familiar with the concrete plant nearby (Kerr Station Road in Cabot is pretty close to the burial site), so he took her there. He had to get rid of her quickly and that was faster than driving around trying to find a spot). If they had all driven in BC's car, then their car was at the Scott house, so while AL buried the body, CL took BCs car back, left it there, and took off. Depending on when her clinicals started, she possibly could have made it. In the chaos, they accidentally ended up with BC's phone. Maybe they didn't realize it for a while and then sent the texts and then took the batteries and SIM out of the phone, but it had already pinged from their home. CL maybe freaked out the next day when AL called the police about the TP rolling, so she got out of there. If the phone's last ping was at or near their home, the police would have been watching both of them. Maybe that's why CL was having her ex drive her around rather than using her own car that might have been seen at the Scott house.
That doesn't explain the open door at the Scott house, but they could have gone in to try to remove fingerprints and then left the door open. Maybe there never was a lockbox. If BC's blood or DNA was on CL's clothing that might explain her arrest after that time period.
Thoughts?? Does my imagination need to take a break?
